It sounds like they missed the mark by not having someone that could answer the hard questions. Kinda the Accenture style model, get the questions then maybe do something about them or toss the baby out with the bathwater. Tongue in cheek!

Perhaps they had an objective that was satisfied by the one-on-one interactions that their employees had with the 30 guests. Might I ask, what did they ask you? Were any of the other guests treated like important clients?
